Advancements in navigational bronchoscopy for peripheral pulmonary lesions: A review with special focus on virtual bronchoscopic navigation.

ABSTRACT: Lung cancer is often diagnosed at an advanced stage and is associated with significant morbidity and mortality. Low-dose computed tomography for lung cancer screening has increased the incidence of peripheral pulmonary lesions. Surveillance and early detection of these lesions at risk of developing cancer are critical for improving patient survival. Because these lesions are usually distal to the lobar and segmental bronchi, they are not directly visible with standard flexible bronchoscopes resulting in low diagnostic yield for small lesions <2 cm. The past 30 years have seen several paradigm shifts in diagnostic bronchoscopy. Recent technological advances in navigation bronchoscopy combined with other modalities have enabled sampling lesions beyond central airways. However, smaller peripheral lesions remain challenging for bronchoscopic biopsy. This review provides an overview of recent advances in interventional bronchoscopy in the screening, diagnosis, and treatment of peripheral pulmonary lesions, with a particular focus on virtual bronchoscopic navigation.

Project description:Objective:Fluoroscopy guidance is generally required for endobronchial ultrasonography with guide sheath (EBUS-GS) in peripheral pulmonary lesions (PPLs). Virtual bronchoscopic navigation (VBN) can guide the bronchoscope by creating virtual images of the bronchial route to the lesion. The diagnostic yield and safety profiles of VBN without fluoroscopy for PPLs have not been evaluated in inexperienced pulmonologist performing EBUS-GS. Methods:Between January 2016 and June 2017, consecutive patients with PPLs referred for EBUS-GS at a single cancer center were enrolled. The diagnostic yield as well as safety profiles was retrospectively analyzed, and our preliminary experience was shared. Results:A total of 109 patients with 109 lesions were included, 99 (90.8%) lesions were visible on EBUS imaging. According to the procedure time needed to locate the lesion on EBUS, 24.8% (27/109) were deemed technically difficult procedures; however, no significant relationships were identified between candidate parameters and technically difficult procedures. The overall diagnosis yield was 74.3% (81/109), and the diagnostic yield of malignancy was 83.7% (77/92). Lesions larger than 20 mm [odds ratio (OR), 2.758; 95% confidence interval (95% CI), 1.077-7.062; P=0.034] and probe of within type (OR, 3.174; 95% CI, 1.151-8.757, P=0.026) were independent factors leading to a better diagnostic yield in multivariate analysis. About 30 practice procedures were needed to achieve a stable diagnostic yield, and the proportion of technically difficult procedures decreased and stabilized after 70 practice procedures. Regarding complications, one patient (0.9%) had intraoperative hemorrhage (100 mL) which was managed under endoscopy. Conclusions:VBN without fluoroscopy guidance is still useful and safe for PPLs diagnosis, especially for malignant diseases when performed by pulmonologist without previous experience of EBUS-GS. VBN may simplify the process of lesion positioning and further multi-center randomized studies are warranted.
